CDS-5000 pyrolyser range

Analytical pyrolysis requires accurate control of pyrolysis temperature, pyrolysis time, and temperature ramp rate, the Model 5000 series provides control of all three parameters. Analytical runs may be programmed for up to eight steps per sample, with automatic control of the on-line valve, interface temperature, GC ready sensing and GC start for each step. When configured with the trapping option, the Pyroprobe® may be used to collect analytes from slow rate pyrolysis, evolved gas analysis, thermal desorption or reactant gas pyrolysis. The unique interfacing design permits a direct pyrolysis path to the GC inlet or rapid sample heating and transfer to the trap without interrupting the pneumatics of the GC. The transfer line can be co-installed with a GC liquid autosampler. The interface for the model 5000 can be removed easily in a few minutes if required, the transfer line for the model 5150 and 5200 can be removed in under 15 seconds . Simple PC control of all parameters is presented in an easy to program window, permitting method development, storage, notation and editing

CDS desorption system

Desorption and trap
The 5200 may use a desorption tube instead of the Pyroprobe filament rod for heating a sample. The desorption tube attaches pneumatically to the desorption probe, which brings flow through the tube and then to the trap of the 5200

CDS quick connect system

Fast connection to GC inlet
The Quickconnect transfer line is available for most GC inlets and allows the user to switch from pyrolysis mode to GC liquid autosampler mode in under 30 seconds

System control

CDS pyrolysis control software

The CDS 5000 series pyroprobes are controlled via PC software that provides direct control of all heated temperature zones and automatic timed events. The software co-resides with the GC and GCMS software and displays real time temperatures during the pyrolysis run
